Earth Science - Water Resources

Multiple Choice

Natural resources that cannot be reused or replaced in a person's lifetime are resources.

• Renewable

• Nonrenewable

• Inexhaustible

• Unnatural

Multiple Choice

What term refers to a natural resource that is continually renewed?

• Hydrosphere

• Natural resources

• Renewable resource

• Pollution

Multiple Choice

What term refers to any natural material or energy source that is used by humans?

• Hydrosphere

• Natural resources

• Renewable resource

• Pollution

Multiple Choice

What term refers to the oceans and all the other water on the planet, including in the atmosphere?

• Hydrosphere

• Natural resources

• Renewable resource

• Pollution

Multiple Choice

What is an aquifer?

• The water that is beneath Earth's surface

• All the bodies of freshwater, salt water, ice, and snow that are found above the ground

• The area of land that is drained by a river system

• A body of rock or sediment that stores groundwater and allows the flow of groundwater

Freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare. Only 3% of the world’s water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use.

​

Multiple Choice

What % of freshwater is on Earth?

• 97%

• 71%

• 3 % 

• 1 %

Multiple Choice

2/3 of freshwater on Earth is "locked away" in what water source location?

• atmosphere

• rivers and lakes

• underground

• ice and glaciers

Multiple Choice

What two elements make up water?

• Helium and oxygen
• Hydrogen and oxygen
• helium and carbon
• oxygen and carbon

Multiple Choice

Attractions between water molecules are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

Multiple Choice

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Hydrogen bonds pull the water molecules like a chain

• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves

Multiple Choice

Large bodies of water can

• keep the temperatureof nearby lands from extremes

• improve the value of nearby lands

• release large amounts of heat energy

• cause temperature extremes in nearby lands

Multiple Choice

The continental effect is

• when there are no large bodies of water near to help regulate the temperature

• when there are large bodies of water near to help regulate the temperature

• When different continents have different climates

• When different continents have similiar climates

Multiple Choice

Evaporative cooling in people is a fancy way of saying that we

• sweat.

• exercise.

• use energy.

• use air conditioners.

Multiple Choice

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, the surface tension of water becomes stronger, allowing it to float.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Multiple Choice

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place

• makes the rocks last longer

• expands, cracks, and breaks rocks

• causes rocks to fall in landslides

Multiple Choice

A city installs water-saving toilets in public buildings. What long-term environmental impact does this decision support?

• Increases fossil fuel demand

• Helps keep freshwater sources renewable

• Reduces the need for clean water

• Uses more energy for water filtration

Multiple Choice

In general, water use worldwide is dominated by

• Agricultural use

• Domestic needs

• Industrial activities

• All of these are sectors that use water about equally

Multiple Choice

What percent of water is used for industrial use?

• 5%

• 23%

• 40%

• 70%

Multiple Choice

What percent of water is used for Agricultural use?

• 5%

• 23%

• 40%

• 70%

• man made lakes used for drinking water, recreation and industry

• hydroelectric power

• existing ecosystems changed, displacing species and humans

• flood control

Multiple Choice

The term for the removal of salts and other minerals from a water source is known as

• virtual water

• gray water

• eutrophication

• desalination
